c# - 建议使用 Nest elasticsearch 创建带有完成的索引

Question

我正在使用 elasticsearc 2.3.3 和 Nest 2.3.2，我需要创建索引。需要将属性映射到类文件中添加的属性。

public class IndexDocument
{
    [Number(Store = true)]
    public long Id { get; set; }
    [String(Store = true, Index = FieldIndexOption.Analyzed, TermVector = TermVectorOption.WithPositionsOffsets)]
    public string Title { get; set; }
    public Attachment File { get; set; }
    [String(Store = true, Index = FieldIndexOption.Analyzed)]
    public string DocumentType { get; set; }
    [String(Store = true, Index = FieldIndexOption.NotAnalyzed)]
    public string DocLocation { get; set; }
    [String(Store = true, Index = FieldIndexOption.Analyzed)]
    public DateTime LastModifiedDate { get; set; }

}

public class Attachment
{
    public Attachment()
    {

    }
    [String(Name = "_content_length", Store = true, Index = FieldIndexOption.Analyzed)]
    public long ContentLength { get; set; }
    [String(Store = true, Index = FieldIndexOption.Analyzed, TermVector = TermVectorOption.WithPositionsOffsets, Name = "_content")]
    public string Content { get; set; }

}

另外我想在文件字段中添加一个完成建议。我是这个弹性搜索的新手。有人可以帮忙吗？

我创建了如下的附件索引。如何使用此附加完成建议和词干分析器代码？

this.client.CreateIndex("mydocs", c => c.Mappings(mp => mp.Map<IndexDocument>
                (m => m.Properties(ps => ps.Attachment
                        (a => a.Name(o => o.File)
                               .TitleField(t => t.Name(x => x.Title).TermVector(TermVectorOption.WithPositionsOffsets))
                               )))));
